Re factions.... trying to anchor 20th century into the past ?

I've been putting my thoughts on paper ( tying to make links with Tradgardland's past and those of her neighbours) and digging out ideas I wrote down last year-here is where we are so far...

Freikorps: a unit equipped in traditional dress (like the lederhosen wearing Freikorps Werdenfelds) to be portrayed by Eureka 1808 Tyrolean figures.
Another unit in late ww1 German uniforms.

Faction ideas so far:

Ducal Army- Duke himself,Guard unit,Militia units-loyal to Duchy
- some units who threw in their lot with revolutionaries

Spartacists-left wing,revolutionary,Russian backed,

Guild/Union militias- Herrring Fisher's Union etc

Sachen-Vindow Freikorps- aristocratic unit from former Duchy led by decedent of the notorious 18th Century Duchess - vile Stagonians and assorted shady characters

Volunteers from the Imperium - led by ex Austro -Hungarian officers who wish to make fortune from the struggles which divide the duchy.

Well here we are at this point in the planning - do let me know what you think!
